SHIELDING APPLIANCE FOR MINE TROLLEY-WIRES.

Specification of Letters Patent. Patented 0013. 16, 1917.

Applicationfiled September 21, 1916. Serial No. 121,474.

To all whom it may concern:

Be it known that I, HARVEY W. REAUME, a citizen of the United States, residing at Brodhead, in the county of Las Animas and State of Colorado, have invented certain new and useful Improvements in Shielding Appliances for Mine TrolleyWVires, of which the following is a specification.

My invention relates to trolleywire shields for use in mines in which the ore or coal is conveyed by means of electrically operated railways.

In order to prevent accidents by contact with the exposed trolley-wires suspended from the roofs of mine-tunnels, it is customwood and then nail boards to the projecting ends of the plugs at opposite sides of the wires.

It is obvious that principally by reason of the irregular formation of mine roofs, and the fragile nature of the plugs, this method of shielding is unreliable and otherwise unsatisfactory, and it is'the principal object of the present invention to provide a simple appliance by which shields may be securely suspended from the hangers used to fasten the trolley wires to the mine-roofs.

Another object of my invention is to provide meansfor the suspension of the shields so that they may be readily moved to alford access to the wire or the hangers for repairs or adjustment.

I attain these objects by the provision of hoods which are adapted for attachment to the hangers by means of which the trolley wires are suspended from the mine roofs, and shields which are hinged to the hoods and which normally hang perpendicularly at opposite sides of the wires.

An embodiment of my invention is shown in the accompanying drawings in the various views of which like parts are similarly designated, and in which Figure 1 represents a longitudinal section through the roof of a mine-tunnel showing my improved shielding-appliance in its 0perative position. with relation to a trolleywire suspended from the roof,

Fig. 2, an enlarged section along the line 2-2, Fig. 1, and

Fig. 3 a section taken on the line 33, Fig. 2.

Referring .to the drawings, the reference numeral 2 designates the roof of a mine-tunnel, and 3 the trolley-wire suspended therefrom by means of hangers 4:.

In the drawings I .have shown my improved shields in connection with hangers of a type commonly used in present mine-railway construction, but I desire it understood that my invention is independent of any particular form of hanger and maybe used effectively in connection with any of the many trolley-wire hangers at present on the market. p

The hangers shown in the drawings are composed of a stem 5 having at its upper end a longitudinally split socket 6 for its rigid connection with a wooden-plug 7 driven into an opening in the roof of the mine tunnel.

The stem has at its lower end, a threaded stud 8 of reduced diameter, for the attachment of a bell 19 which at its lower end carries the clamp 20 in which the trolley wire is secured.

My improved shielding-appliance comprises a hood 9 made of sheet metal and bent to form two divergent side-members 10 and a cross-member 12 connecting the upper edges thereof.

The cross-member 12 has an opening for the reception of the stud 8 at the lower end of the stem 5 and the side members 10 are bent at their lower edges to provide hingeknuckles 13.

Hinge-blades 14 provided with knuckles corresponding with those on the opposite edges of the hood are suspended therefrom by means of pins 15, there being two blades at each side of the hood for the attachment of the ends of the sections 16 of shields made of wood or other suitable material.

The shield-sections are attached to the hinge-blades by means of counter-sunk screws and hang, in practice, perpendicularly from the edges of the hood, it being desirable to construct their hinge-connections so as to prevent or limit their inward motion.

By arranging the shield sections in longitudinal alinement and end-to-end contiguity, the trolley-wires extending between the shields are adequately protected from contact with other objects, it being understood that the hinged connections'of the shieldsections with the hoods permit of their being lifted to aiford across to the wire or the hangers for purposes of adjustment or repairs.

The hoods 10 suspended from the bells which are attached to the screw studs at the lower ends of the stems 4, present a stable medium for the suspensions of the shields 16, and nuts 17 screwed on the studs against the upper surfaces of the cross-members 12 of the hood, are applied to securely fasten the hoods against accidental displacement.

Having thus described my improved shielding appliance in a form designed for use in connection with hangers of the specific construction shown in the drawings, I desire it understood that modifications in the construction and arrangement of its parts, to adapt it for its attachment to hangers of different design, may be resorted to within the spirit of my invention as de= fined in the following claims:

1. In a shielding appliance for mine trolley wires, a hood including downwardly diverging side-members having at their lower ends, means for the attachment of Copies of this patent may be obtained for shields, and a cross-member connecting the upper ends of said side-members and having an opening for the attachment of the hood to 'a hanger by which a trolley-wire is suspended from a mine-roof.

2. In a shielding appliance for mine-trolley wires, a hood including downwardly diverging side-membe'rs, and a cross-member connecting the upper ends of said side-members and having an opening for the attachment of the hood to a hanger by which a trolley-Wire is suspended from a mineroof, and hinge-blades pivotally suspended from the lower ends of said side-members.

3. In a shielding appliance for mine-trolley wires, a hood including downwardly diverging side-members, and a cross-member connecting the upper ends of said side-members and having an opening for the attachment of the hood to a hanger by which a trolley-wire is suspended from a mine-roof,

and hinge-blades pivotally suspended in pairs from the lower ends of said sidemembers.

In testimonywhereof I have affixed my signature in presence of two witnesses. HARVEY IV. REAUME. Witnesses:
